I have made available for free a corrected version of my book “Mathematics of Public Key Cryptography”. You can access it here. I have fixed all the typos and errors that I was aware of (most of them documented in the errata list), plus I have added two or three new examples and exercises. I thank everyone who found errors or gave feedback on the original version.

Sadly, the book is not updated to discuss new research since 2011. I don’t have time to do that.
